EMERY-VVHEEL DRESSER.

Specification of Letters Patent.

Patented Nov. 1, 1921.

Application filed January 13, 1920. Serial No. 351,206.

To all whom it may concern:

Be it known that I, CARL E. Sousa s'rRoM, a citizen of the United States, residing at Muskegon, in the county of Muskegon, and State of Michigan, have invented certain new and useful Improvements in Emery-Wheel Dressers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved emery wheel dresser and one object of the invention is to provide an attachment for the dresser so constructed that particles of emery will be prevented from flying up into the operators face and getting into his eyes. It often happens when dressing an emery wheel that particles of emery will be blown upwardly and thus do damage to the eyes and sometimes cause blindness.

Another object of this invention is to so construct this guard that it may be adjustably held in place and thus permitted to be swung out of the way when it is desired to remove the grinding disks and replace them with new disks.

Another object ofthis invention is to so construct this guard that it may be used in connection with emery wheel dressers of any conventional construction thus making it unnecessary to provide a special construction of dresser.

This invention is illustrated in the accompanying drawing, wherein:

Figure l is a view showing an emery wheel dresser in side elevation and provided with the improved guard.

Fig. 2 is a top plan view of the emery wheel dresser with the guard in place.

Fig. 3 is an end elevation of the dresser.

Fig. 4 is a longitudinal sectional view of the dresser with the guard in place.

This improved guard is used in connection with an emery wheel dresser having a conventional construction and provided with a handle 10 and head 11, the head being provided with the usual side arms 12 which carry the shaft 13 upon which the cutting disks 14 are rotatably mounted.

The guard which is indicated in general by the numeral 15 extends across the head 11 and above the grinding disks and is provided with side wings 16 which extend downwardly along the sides of the arms 12 and along the sides of the forward end portion of the handle 10 and are extended to provide arms 17 through which will pass the end portions of the pin 18. This pin 18 serves to pivotally connect the guards with the handle of the dresser so that the guard may be swung upwardly out of the way and permit the removal of the shaft 13 and disks 14 when it is desired to remove the disks and exchange them for new ones. In order to releasably hold the guard in operative position there has been provided a threaded stem 19 which extends through the head 11 and through the guard and carries a winged nut 20 which is removable. It will thus be seen that the nut may be removed and the guard swung upwardly and after the new disks have been put in place the guard swung downwardly to the operative position and the securing nut then screwed tightly in place. WVith this guard in place the emery wheel dresser may be used in the usual manner and the fine particles of emery which are thrown upwardly will strike the guard and thus be deflected and caused to drop downwardly instead of flying upwardly and striking the operator in the face or getting into his eyes. It will thus be seen that the operators eyes will be protected from possible injury by the particles of emery. 1

IV hat is claimed is:

The combination with an emery wheel dressing tool having a handle provided with a bifurcated head rotatably supporting a dressing element and said head having a vertical opening arranged rearwardly of the bifurcation, of a guard disposed over the head and handle and including side and top walls, said top wall having its forward portion inclined upwardly and disposed over the dressing element, said side walls being arranged over the sides of the head and extended rearwardly beyond the rear end of the top wall to form arms, means pivotin'g the arms to the handle, a bolt in said opening and extending through the top wall of the guard, and a nut on said I bolt for engagement with the guard.

In testimony whereof I afiix my signature in presence of two witnesses.
